I need the adjoint gradients of both drag and lift. I can get the drag gradient or lift gradient by changing OBJECTIVE_FUNCTION= DRAG or OBJECTIVE_FUNCTION= LIFT in the config file. What can I do to get the gradients of both? Whatever I try I get the error: OBJECTIVE_FUNCTION: multiple values for type enum.

Hi Ry10,
like you already noticed, it is not possible to get both gradients at once. You have to do two separate runs. One with OBJECTIVE_FUNCTION=DRAG and one with OBJECTIVE_FUNCTION=LIFT. |
